Make sure that you keep your antivirus updated
New viruses come out every minute, so it is essential that you have the latest signatures for your antivirus program to provide you with the best possible protection from malicious softwareNote: You should only have one antivirus installed at a time. Having more than one antivirus program installed at once is likely to cause conflicts and may well decrease your overall protection as well as impairing the performance of your PC.

Make sure you install all the security updates for Windows, Internet explorer & Microsoft Office
Whenever a security problem in its software is found, Microsoft will usually create a patch for it to that after the patch is installed, attackers can't use the vulnerability to install malicious software on your PC, so keeping up with these patches will help to prevent malicious software being installed on your PC
Go here to check for & install updates to Microsoft applicationsNote: The update process uses activex, so you will need to use internet explorer for it, and allow the activex control that it wants to install

Keep your non-Microsoft applications updated as well
Microsoft isn't the only company whose products can contain security vulnerabilities, to check for other vulnerable programs running on your PC that are in need of an update, you can use the Secunia Software Inspector - I suggest that you run it at least once a month

Make Internet Explorer more secure
Click Start > Run
Type Inetcpl.cpl & click OK
Click on the Security tab
Click Reset all zones to default level
Make sure the Internet Zone is selected & Click Custom level
In the ActiveX section, set the first two options ("Download signed and unsigned ActiveX controls) to "Prompt", and ("Initialize and Script ActiveX controls not marked as safe") to "Disable".
Next Click OK, then Apply button and then OK to exit the Internet Properties page.

Install SpywareBlaster & make sure to update it regularly
SpywareBlaster sets killbits in the registry to prevent known malicious activex controls from installing themselves on your computer.
If you don't know what activex controls are, see here
You can download SpywareBlaster from here

Install and use Spybot Search & Destroy
Instructions are located here
Make sure you update, reimmunize & scan regularly

Make use of the HOSTS file included with Spybot Search & Destroy
Every version of windows includes a hosts file as part of them. A hosts file is a bit like a phone book, it points to the actual numeric address (i.e. the IP address) from the human friendly name of a website. This feature can be used to block malicious websites
Spybot Search & Destroy has a good HOSTS file built in, to enable the HOSTS file in Spybot Search & Destroy

Run Spybot Search & Destroy

Click on Mode, and then place a tick next to Advanced mode

Click Yes

In the left hand pane of Spybot Search & Destroy, click on Tools, and then on Hosts File

Click on Add Spybot-S&D hosts list

Note: On some PCs, having a custom HOSTS file installed can cause a significant slowdown. Following these instructions should resolve the issue

Install a-squared Free & update and scan with it regularly
a-squared free is a product from Emsi Software provided free for private use that can detect and remove a variety of malicious software. You can get it hereNote: If you have a dialup internet connection, you may also like to install a-squared Anti-Dialer which provides some real time protection against premium rate dialers

Finally I am trying to make one point very clear. It is absolutely essential to keep all of your security programs up to date
